Bolt Pretension often takes a lot of iterations to converge before an external load can be applied, which only takes a few more iterations to finish that load case.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Say you have to solve three models: one for X, Y and Z directions of gravity or force,<\/p>\n
<\/p>\n
and it takes an hour to solve bolt pretension in step 1 but only a minute to apply the load in step 2.<\/p>\n
<\/p>\n
This takes three hours and three minutes of solve time when done in the normal way.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Now you can do it in one hour and three minutes of solve time, plus a few quick manual steps.<\/p>\n
<\/p>\n
It uses a command snippet, Read Results, the Activate load capability and a Restart.<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
Start with a 2 step model that solves without any issues. Put all the independent loads that you want in that model.<\/p>\n
